Murray has won the Miami tournament twice, in 2009 and 2013. Djokovic has taken the title for five of the last six years, including the last three editions.

According to French newspaper Le Parisien, Djokovic is also a doubt for Miami, also due to a right elbow injury. The newspaper reports Djokovic travelled from Indian Wells to Monaco on Friday to have the injury assessed by his doctor.

The men's singles at the Miami tournament begins on Wednesday, with the event running to April 2.
